276 INTERNAL SECRETIONS 



only by the assumption that a relatively increased number of 

 primary oocytes proceed to develop till the normal number of 

 follicles is attained. Since a similar conclusion can be drawn 

 from the experiments of Lauche on the frog (see above), it 

 seems very likely that the same quantitative law holds for all 

 vertebrates. 



We have already pointed out the fact that testicular hyper- 

 trophy is b}^ no means a compensatory one caused by an 

 increased demand for sex hormones after partial castration. 

 There is likewise no reason to explain by such an assumption 

 the increased follicular development in an ovarian fragment.
